Error compiling USD v20.05 with Python 3.7.4 installed.

[ChokmahBinah]

Description of Issue

Hello,

I am trying to compile USD v20.05. I previously checked dependencies ans it seems ok. I installed Python 3.7.4. When compiling USD using command prompt and pyhton building script, I get this error :

ERROR: 'utf-8' codec can't decode byte 0x82 in position 50: invalid start byte

I don't know for now why it happens. (Before I built USD 20.02 with Python 27 only, and i worked fine)

Perhaps I forgot to specify I use Python 3.7.4 now, and I don't know how to do this if so.

I will try to test compoling using python 2.7. But I anyone have any clues, I would be delighted ^^

Thank you in advance :)

Florian.

Compiling with Python2.7 worked like a charm. Only a tiny problem : Build fails when setting target directory for USD as "C:\Program Files\USD". I had to set target directory as "C:\USD" and it worked.

But when using Python 3.7.4 I still have the same problem as above.

After some researches, perhaps it could be due to my Windows 10 regional settings ?

Hi @ChokmahBinah, could you post the logs showing the backtrace from your builds? The Python 3 issue does seem to be related to your locale, what is that set to? In Python you can do the following to check:

import locale
locale.getdefaultlocale()

Hello @sunyab and @jilliene ,

I added my System Information in my first message hoping it could help.

And here my locales :

C:\Program Files\Python37>python Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

import locale locale.getdefaultlocale() ('fr_FR', 'cp1252')

Here the only log I can get : C:\USD-master\build_scripts>python build_usd.py --tests --openvdb --prman --prman-location "C:\Program Files\Pixar\RenderManProServer-23.2" --alembic "C:\USD" --build-args boost,"--with-date_time --with-thread --with-system --with-filesystem"

Here is the zlib log I found : log.txt It seems to be ok.

The problems seems to appear at boost installation.

But I really don't, I am pretty new to this kind of stuff =$

Hello, I finally manage to compile USD 20.05 with Python 3.7.4.

I used Visual Studio 2017 Developer Command Prompt v15.9.20 as before.

Here is the line I replaced at lines 255/256 in the build_usd.py script :

I launched kitchen stage and tit worked like a charm. I lauched the interpreter command to verify that it was really using Python 3.7.4.

I hope it would help.

Thank you a lot for all this USD stuff ^^

I have same problem on Python 3.8.3

import locale locale.getdefaultlocale() ('ru_RU', 'cp1251')

@ZeroSOFAD , Did you trying to modify the build_usd.py script as I mentionned ? I am curious if it could work for anyone else ? ...

[ZeroSOFAD]

@ChokmahBinah Yes, but not worked for me. All dependencies installed success. But when installing USD error occurred.

------ERROR----- STATUS: Installing USD... ERROR: 'charmap' codec can't decode byte 0x98 in position 30480: character maps to

[ZeroSOFAD]

@ChokmahBinah And yet your method works! line 255/256 in the build_usd.py script

------CODE in build_usd.py------------

encoding = sys.stdout.encoding or "UTF-8"

encoding = "Windows-1251" ------CODE in build_usd.py------------

I reinstalled Python and Visual Studio

In the beginning not working with Python 3.8.3 Visual Studio 16 2019

And then installed and working. Python 3.7.4 Visual Studio 14 2015

[meshula]

Python 3.8 isn't supported by USD on Windows yet. I think you might also have success with Python 3.7 and Visual Studio 16 2019.

[ZeroSOFAD]

I tried it like this Python 3.7.4 Visual Studio 16 2019

it doesn’t work!
